Abstract: The preliminary design of a dike field at Redeye Crossing on the Mississippi River (Baton Rouge, Louisiana) is discussed. The TABS-2 modeling system was used to develop a two dimensional sediment transport model of the Mississippi River from River Mile 228 downstream to 206. Numerical model results are presented. The numerical modeling effort included dynamic simulations two years long to evaluate the impact of proposed dike field layouts on dredging requirements. An assessment of the model's applicability to the design of dike fields consisting of submerged rock dikes and model limitations encountered during the study are presented.
